ABSTRACT:
A capsule-like cartridge comprising a cylindrical body of uniform diameter open at one end and provided with an annular flange surrounding the open end, the other end being closed by an integral hemi-spherical end of the same radius as said body and provided with an angularly extending discharge nipple communicating with the interior of the hemi-spherical end and body. After the body is loaded with a precisely measured quantity of material, the open end is closed by a plug slidably movable along said body when one end is engaged by a plunger of no greater diameter than said plug and the opposite end being complementary in shape to the hemi-spherical end of the body, whereby the plunger is capable of discharging the entire measured amount of material in the body except the scintilla thereof lodged in the nipple. The body and plug are molded from opaque material impervious to the passage of light and the tip of the nipple is closed by a cap which may be color-coded to indicate various facts as kind of material, weight or quantity, or otherwise.
